Abstract
The utility model discloses an exhaust structure of a compressor, which includes a valve seat positioned at an exhaust port of the compressor, an elastic valve plate and a lift limit part, wherein the lift limit part is a sheet-shaped body with one end warping upwards; and further, the elastic valve plate is positioned on the inner side of the lift limit part, and is fixed beside the valve seat together with the lift limit part through fixing parts. The exhaust structure of the compressor is characterized in that the elastic valve plate includes a first elastic valve plate and a second valve plate that are stacked, and the first elastic valve plate is matched with the valve seat. According to the exhaust structure of the compressor, through the manners that the first elastic valve plate and the second elastic valve plate are stacked and the first elastic valve plate is matched with the valve seat, namely through adopting two layers of elastic valve plates (exhaust valve plates), the sound that the elastic valve plates impact the lift limit part can be reduced efficiently, the sound that the elastic valve plates act on the valve seat can be reduced, the noise of the compressor is lowered, and the efficiency of the compressor is improved at the same time.
Description
Technical field
The utility model relates to a kind of rotary compressor, and is especially relevant with the discharge portion of rotary compressor.
Background technique
Along with the miniaturization of compressor design, the reduction difficulty of compressor noise is increasing, and the terminal use is also responsive all the more for the noise of terminal equipments such as air conditioner.
The rotary compressor of general design; Its exhaust structure comprises the valve seat that is positioned at exhaust ports, elastic valve plate and lift limited part; The lift limited part is one one laminar body that end is upturned; Elastic valve plate is positioned at the inboard of lift limited part, is fixed on the side of valve seat with the lift limited part through fixed block, and elastic valve plate cooperates with valve seat.The effect of above-mentioned compressor exhaust structure mainly is to be used to prevent that pressurized gas from the end flowing backward in the cylinder in the compression of compressor.The above-mentioned compressor exhaust structure only is provided with an elastic valve plate, find in actual use, this elastic valve plate by jack-up or falling process in, can produce high frequency noise.This shows that rotary compressor exhaust structure of the prior art awaits further to improve.
The model utility content
The task of the utility model is to solve the technological deficiency of the exhaust structure existence of rotary compressor in the existing technology, and a kind of compressor air-discharging structure is provided.
Its technical solution is:
A kind of compressor air-discharging structure; Comprise the valve seat, elastic valve plate and the lift limited part that are positioned at the exhaust outlet of compressor place; The lift limited part is one one laminar body that end is upturned; Elastic valve plate is positioned at the inboard of lift limited part, is fixed on the side of valve seat through fixed block with the lift limited part; Above-mentioned elastic valve plate comprises first elastic valve plate and second elastic valve plate that is stacked together, and wherein first elastic valve plate cooperates with valve seat.
Above-mentioned first elastic valve plate is positioned at the inboard of second elastic valve plate, and second elastic valve plate is close on the outer surface of first elastic valve plate.
The utlity model has following useful technique effect:
The utility model adopts first elastic valve plate and second elastic valve plate that is stacked together; And the mode that cooperates with valve seat by first elastic valve plate; Promptly adopt the mode of two-layer elastic valve plate (exhaust valve plate), can reduce the sound that elastic valve plate bounces the lift limited part effectively, and improve elastic valve plate and act on the sound on the valve seat; When helping reducing compressor noise, also has the effect that improves compressor efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural principle schematic representation of a kind of mode of execution of the utility model.
Fig. 2 is the decomposing state figure of Fig. 1 mode.
Phase diagram when Fig. 3 is in the exhaust operating mode for Fig. 1 mode.
Embodiment
In conjunction with Fig. 1, Fig. 2 and Fig. 3; A kind of compressor air-discharging structure; Comprise the valve seat 1, elastic valve plate and the lift limited part 2 that are positioned at the exhaust outlet of compressor place; The lift limited part is one one laminar body that end is upturned, and elastic valve plate is positioned at the inboard of lift limited part, is fixed on the side of valve seat through fixed block 3 with the lift limited part.Above-mentioned elastic valve plate comprises first elastic valve plate 4 and second elastic valve plate 5 that is stacked together, and wherein first elastic valve plate cooperates with valve seat.Above-mentioned first elastic valve plate is positioned at the inboard of second elastic valve plate, and second elastic valve plate is close on the outer surface of first elastic valve plate.
In the aforesaid way, the structure of first elastic valve plate and second elastic valve plate and shape both can be identical, also can be inequality.
The working principle and the process of the utility model roughly are:
Compressor pressurized gas when compression end of a period exhaust backs down first, second elastic valve plate; First elastic valve plate pushes up second elastic valve plate to the position of lift limited part; Be attached to until second elastic valve plate on the internal surface of lift limited part; In this process,, thereby can the noise differentiation be reduced because the time of first, second elastic valve plate arrival top dead center is inconsistent.
First elastic valve plate is back to the valve seat position in advance when backhaul, seals valve seat and flows backward to cylinder to prevent pressurized gas, realizes the main by function of elastic valve plate, and second elastic valve plate postpones some slightly and rebounds and slap against on first elastic valve plate.
The utility model adopts the design of double-deck elastic valve plate, has improved the movement locus of valve block, has a better role for the raising tool of valve block reliability.Simultaneously, owing to changed the backhaul travel track of valve block, the working life that also can improve valve seat, thereby the whole reliability of raising compressor.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
